[編輯]描述Troughs in Sputnik Planum by LORRI - crop of PIA19936.jpg |
English: UPLOADER NOTES: This is a crop of PIA19936 which covers the same area as PIA19841, but at higher resolution. The original NASA image was modified by the uploader as follows: the image was rotated 50 deg. clockwise, cropped, the linear pixel dimensions were increased by 50%, contrast was increased, brightness decreased, highlights were darkened, midtone contrast was increased, a scale inset was added, and the image was converted from TIFF to JPEG format.
The original NASA caption for PIA19936 is as follows: "Mosaic of high-resolution images of Pluto, sent back from NASA's New Horizons spacecraft from Sept. 5 to 7, 2015. The image is dominated by the informally-named icy plain Sputnik Planum, the smooth, bright region across the center. This image also features a tremendous variety of other landscapes surrounding Sputnik. The smallest visible features are 0.5 miles (0.8 kilometers) in size, and the mosaic covers a region roughly 1,000 miles (1600 kilometers) wide. The image was taken as New Horizons flew past Pluto on July 14, 2015, from a distance of 50,000 miles (80,000 kilometers). The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, designed, built, and operates the New Horizons spacecraft, and manages the mission for NASA's Science Mission Directorate. The Southwest Research Institute, based in San Antonio, leads the science team, payload operations and encounter science planning. New Horizons is part of the New Frontiers Program managed by NASA's Marshall Space Flight Center in Huntsville, Alabama." The original NASA caption for PIA19841 is as follows: "In the center left of Pluto's vast heart-shaped feature -- informally named "Tombaugh Regio" -- lies a vast, craterless plain that appears to be no more than 100 million years old, and is possibly still being shaped by geologic processes. This frozen region is north of Pluto's icy mountains and has been informally named Sputnik Planum (Sputnik Plain), after Earth's first artificial satellite. The surface appears to be divided into irregularly-shaped segments that are ringed by narrow troughs. Features that appear to be groups of mounds and fields of small pits are also visible. This image was acquired by the Long Range Reconnaissance Imager (LORRI) on July 14 from a distance of 48,000 miles (77,000 kilometers). Features as small as one-half mile (1 kilometer) across are visible. The blocky appearance of some features is due to compression of the image. To see an annotated version of this image, see PIA19714" |
